[PATCH] qemu-arm: Enable NVMe for distro boot

[Mark Kettenis]

> From: Alexander Graf <agraf at csgraf.de>

> 
> We already support the NVMe commands and PCIe backend in the QEMU target,
> so let's make it easy for anyone to consume them and enable NVMe distro
> boot along the way!
> 
> With this patch, I can put an NVMe backed disk image into my QEMU VM and
> have it automatically load a UEFI target blob.
